1 Claim. (01. 285-120) This invention relates to a'lead pipe ferrule of this invention and which is attained by the designed for use in connection with the replaceemployment of a ferrule of the form as hereinment of pipes employed when repairing municiafter referred to. pal water supply lines, and has for its primary ob- A further object of the invention is to provide,

ject to materially reduce the cost of upkeep and a in a manner as hereinafter set forth, a ferrule for 60 saving in fittings with respect to supply lines of the purpose referred to for providing a water-' the class referred to. proof joint holding against anypressure from As is well known a municipal water supply line the line Without the employment of a gasket, includes what is termed a municipal or corporawasher, solder or hot metal.

tion cock which is secured into the wall of the The invention further aims to provide, in a 65 main water line and what is termed a municipal manner as hereinafter set forth, a lead ferrule for or corporation stop cock at the curb line to the purpose referred to which is simple in its conwhich the house line is connected. The cocks struction, strong, a l p thoroughly when originally installed are connected together efficient Wh u Conveniently installed by a lead pipe. Further that the work of the applied and comparatively inexpensive to 70 municipality or corporation in conveying water manufacture. to the premises ends at the curb. Up to recent To the above ends essentially and others which date, lead pipe has been used in conveying water m y hereinafter pp the invention Co sts of from the main line tothe curb. After aperiod the construction of a ferrule falling within the of use the lead pipe becomes impaired, due to the S0Op 0 the invention as C i d- 75 wail thereof becoming coated with lime or other In the drawin 7 hard sediment. Further it is well known that Fi ure 1 i an elevation of a main line c upon certain conditions lead pipe has become a curb stop cock, a copper pipe connection begranulated or disintegrated within three or four tween said cocks and the adaptation of a pair years. When the lead pipe becomes impaired, of ferrules, in accordance with this invention with so granulated or disintegrated, removal thereof is respec to ai p p and OOCKS- required and a new pipe substituted.

The threads on the inner n I c are ms a e 0 ace of each sleeve are designated 10. a have fitted thereto the copper pipe is the aim The pipe 3 at each end, only one end being 110.

shown is formed with an outwardly directed annular flange 11. Each end flange 11 is for seating in a rabbet 12 formed in the inner end of the cylindrical body part 12 of the ferrule 13. The rabbet '12 borders the inner face of body part 12'. An outwardly directed annular flange 14 is provided at the inner end of body part 12 and the flange 14 preferably is of greater thickness than that of said body part and the latter is open at each end. The inner face of flange 11 is flush with the inner face of flange 14 when the pipe 3 and a ferrule 13 are coupled together.

A flanged sleeve 15 is mounted in encompassing relation with respect to body part 12. The flange on sleeve 15 is designated 16, is of annular-form.

and extends from the inner end of the sleeve. The flange 16 abuts the outer face of flange 14.

The outer end of sleeve 15 is flush with the outer end of body part 12 of the ferrule. The edgesof flanges 14 and 15 are flush with each other. The pipe 3 and flange 14 abuts the outer end of an extension 4 or 5. The diameter offlangel4lor 16 is less than the diameter of the outer end of extension 4 or 5. The flange 16 has its outer face engaged by flange 9 of a collar 8 when one end of pipe 3 and a ferrule, 13 is coupled to an extension 4 or 5. The flanged collar 8 in connection with the flanges 11, 141 and 16 provide for a water tight joint between one end-of pipe 3 and one of the cocks and such joint isobtained without the us of gaskets, washers, solder or hot Imetal.

What I claim is:-

In combination, a corporation cock having a peripherally threaded tubular extension formed with a flat outer end edge, a pipe having its inner diameter corresponding to the inner diameter of said extension and its outer diameter materially less than the outer diameter of said extension, said pipe having one end provided with an outwardly directed flat annular flange seated against said end edge, a lead ferrule including a body part of greater thickness than the body part of the pipe, snugly encompassing the latter, having one end; edge seating against said flange and provided with an outwardly directed annular flange overlapping and enclosing said pipe flange and bearing against saidouter end edge, said ferrule flange being of greater thickness and width than the thickness of theibodypart of the ferrule and of materially less length than the body part of the latter, a sleeve mounted on the body part of the ferrule and formed with an outwardly extending flange abutting the flange of the ferrule, the outer diameter of'the sleeve being less than the outer diameter ofsaid extension, and a.flanged collar having its flange bearing against the flange of the sleeveQsaid; collar adjustably and threadedly ene gaging with said extension for clamping the pipe flange and ferrule flange against said flat outer end edge.
